Abstract (en)

[origin: WO9833974A1] The invention concerns a method and an equipment in the forming of a lead-in strip (A) in a paper/board machine. In the method, two cutters (C1, C2) are used, of which at least one cutter (C2), which is brought into connection with the web from outside the web, is a liquid cutter, preferably a water cutter. In the method, by means of the first cutter (C1) a first cut (f1) is made, and by means of the second cutter (C2) a second cut (f2) is made into the paper/board web (W). In the method, the cutting jet (U2) of said second cutter (C2) is passed into connection with the web (W) from outside the web, in which connection an edge strip (B) is formed alongside the lead-in strip (A). The edge strip (B) has a sharp tip (100), in which case no notch or tail is formed into the lead-in strip (A), which notch or tail might reduce the strength of the lead-in strip (A).
